“Animals have very different sensory, perceptive abilities to us. In some cases they’re better and in some cases they’re worse, but in all cases they’re different,” says Matthew Savoca at the NOAA Southwest Fisheries Science Center in Monterey, California.

One explanation is that animals simply mistake plastic for familiar food items – plastic pellets, for example, are thought to resemble tasty fish eggs. But as humans we are biased by our own senses. To appreciate animals’ love of plastic, scientists must try to view the world as they do.

Humans are visual creatures, but when foraging many marine animals,

, rely primarily on their sense of smell. Savoca and his colleagues have conducted experiments suggesting that some species of
seabirds
and are attracted to plastic by its odour. Specifically, they implicated dimethyl sulfide (DMS), a compound
known to attract foraging birds
, as the chemical cue emanating from plastic. Essentially, algae grows on floating plastic, and when that algae is eaten by krill – a major marine food source – it releases DMS, attracting birds and fish that then munch on the plastic instead of the krill they came for.

Even for vision, we can’t jump to conclusions when considering the appeal of plastic. Like humans, marine turtles rely primarily on their vision to search for food. However, they are also thought to possess the capacity to see UV light, making their vision quite different from our own.

Qamar Schuyler at The University of Queensland, Australia, has got into turtles’ heads by
modelling their visual capabilities
and then measuring the visual characteristics of plastics as turtles see them. She has also examined the stomach contents of deceased turtles to get a sense of their preferred plastics. Her conclusion is that while young turtles are relatively indiscriminate, older turtles preferentially target soft, translucent plastic. Schuyler thinks her results confirm a
long-held idea
that turtles mistake plastic bags for delicious jellyfish.

Colour is also thought to factor into plastic consumption, although preference varies between species. Young turtles prefer white plastic, while Schuyler and her colleagues found that seabirds called shearwaters opt for red plastic.

Besides sight and smell, there are other senses animals use to find food. Many marine animals hunt by echolocation, notably toothed whales and dolphins. Echolocation is known to be incredibly sensitive, and yet dozens of sperm whales and other toothed whales have been

with stomachs full of plastic bags, car parts and other human detritus. Savoca says it’s likely their echolocation misidentifies these objects as food.

Welcome to
subversion.apache.org
, the online home of the Apache Subversion™ software project. Subversion is an open source version control system. Founded in 2000 by CollabNet, Inc., the Subversion project and software have seen incredible success over the past decade. Subversion has enjoyed and continues to enjoy widespread adoption in both the open source arena and the corporate world.

Jane Devonshire, aged 19, was killed at work in August 2015 when the rubbish truck she was working on crashed on a steep suburban street in Birkenhead, Auckland. Four parties – rubbish contractors Veolia (formerly Onyx), truck owner Truck Leasing Ltd, mechanics NP Dobbe Maintenance, and Auckland Council – were charged under the HSE Act in relation to the accident. Three defendants admitted the charges; TLL pleaded not guilty but was convicted in October last year. JACKIE BROWN-HAYSOM talked to Jane’s mother, Rona Topia.

As well as News (Alert24 Safeguard Update, online and in print) and Inspiration/Best Practice (Safeguard magazine in print and online) we have
